I give 2.5 stars if I could .. Not being very delicate, he found that after some uses, screwdriver bits will be somewhat eroded, result: some screws are too damaged to be unscrewed. In short, if the screwdriver should be used only 1 time, they will be perfect. But long term, they become quite fragile. However, considering the price, it's still satisfying, not to mention a rather fast delivery!
